18GHz Ku-Band fiber optic mini Transmitter and Receiver set.
The transmitter is able to accept RF signals from 10mhz to 18Ghz analog or digital RF modulated signal and convert it to an optically modulated light; and the receiver converts the optical signal back to an electrical RF.
There are a lot of challenges to sending high-frequency RF over long-distance coaxial copper cable, the K-Band TX/RX allows you to send this signal over fiber from 0 to 40Km if needed.
Electrical to optical conversion is transparent, protocol or modulation independent, they work with analog or digital modulation standards.
Used for C-band, L-band, Ku-band, S-band Sattelite, cell phone 5G/4G/3G Mobile Communication, DAS or radar applications.
Applications:
5G/4G/3G Mobile Communication

S-Band RF over fiber optic cable transport system. Can be customized for transport distances of up to 150 Km. Can also provide LNB power at various voltages.
4GHz Mini Analog RF over fiber transport equipment. Transmitter has SMA 50ohm electrical interface and accepts Analog RF signal up to 4000Mhz, units come standard with optical FC/APC output. The receiver accepts an optical signal from it's FC/APC port and converts it back to the electrical RF. These units are ideal for transporting high frequency RF over fiber where copper can not complete the application due to its inherent distance limitations.
